AsSelfAwareableEnumTrait lets code that receives an enum class ask what kind of enum it is.

use Phil\Enums\Traits\AsSelfAwareableEnumTrait;

enum HttpStatus: int
{
    use AsSelfAwareableEnumTrait;

    case OK = 200;
    case NOT_FOUND = 404;
}

enum Direction
{
    use AsSelfAwareableEnumTrait;

    case NORTH;
    case SOUTH;
}

`isBacked()`	is backed, by any type	`true`	`false`
`isBackedByInteger()`	is backed by `int`	`true`	`false`
`isBackedByString()`	is backed by `string`	`false`	`false`
